Come to think of it, our road sign in our country really are more then what it means. If you think deeper, it actually telling us "we have chances, we can make it different, don't give up"

ROUND ABOUT

Why do we have round about? it for us to make a right turning, sometime we might make a mistake and turn it to the wrong exit, but there's always another round about in front of us, use it, and it will lead you to the right direction, and make thing different.

STOP SIGN

when it says, "stop" means "stop", do not step forward, accident might happen, unforsee incident will happen, thus when it's time to stop just stop, U turn, meet the round about and turn it to the right direction, if the exist it's not what you want, there's always a U turn sign, there's always a round about to lead you to the right direction. So Friend, look forward, and yes, you have done some mistake, and you noticed, so, U turn, you are not a looser, you are still finding the right direction for yourself, and we do believe that you will, one day, that one day will happen.
